Relaying in a device-to-device communication system

A method of wireless communication at a relay user equipment (UE), comprising:

• receiving, on at least one sidelink channel, a scheduling request from a remote UE;
• determining, by the relay UE, a resource grant for the remote UE in response to receiving the scheduling request;
• and
• transmitting, on one or more sidelink channels, a scheduling indication including the resource grant to the remote UE.

A remote user equipment (UE) for wireless communication, comprising:

• a memory;
• and
• a processor in communication with the memory, wherein the processor is configured to:
• transmit, on at least one sidelink channel, a scheduling request to a relay UE connected with a network entity;
• and
• receive, on one or more sidelink channels, a scheduling indication including a resource grant from the relay UE in response to transmitting the scheduling request.

A relay user equipment (UE) for wireless communication, comprising:

• means for receiving, on at least one sidelink channel, a scheduling request from a remote UE;
• means for determining, by the relay UE, a resource grant for the remote UE in response to receiving the scheduling request;
• and
• means for transmitting, on one or more sidelink channels, a scheduling indication including the resource grant to the remote UE.

A computer-readable medium storing computer executable code for wireless communications at a relay user equipment (UE), comprising code for:

• receiving, on at least one sidelink channel, a scheduling request from a remote UE;
• determining, by the relay UE, a resource grant for the remote UE in response to receiving the scheduling request;
• and
• transmitting, on one or more sidelink channels, a scheduling indication including the resource grant to the remote UE.
